Krill fishing in Antarctica reached a record in the 2024–2025 season, with more than 518,000 tons caught by July. This amount was already 84 percent of the 620,000-ton limit set by global rules. The heavy catch may cause an early suspension if the maximum is reached. Krill, a small crustacean, is important as food for whales, seals, and penguins in the Southern Ocean. Studies also showed that krill help remove about 20 million tons of carbon from the air every year, equal to five million cars. The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) manages the fishing, but talks in 2024 failed to reach an official agreement on quotas and protected areas.

The large catch brought both gains and challenges. Industry groups said the harvest is still suitable, based on studies of krill numbers. On the other hand, environmental groups expressed strong opposition, saying heavy fishing in small zones may trap whales in nets. Experts explained that krill act as a natural barrier against climate change, so their survival is very important. Without stronger conservation, krill may face a fast decline, harming the balance of the ocean system. The future of Antarctic resources depends on cooperation among countries.
